Security Advisories and Notifications


Security Advisory: (BEA05-96.00)

From: Oracle Corporation

Minor Subject: The passphrase for the private key used in the configuration of SSL appears in cleartext when creating a WebLogic Server domain using the Configuration Wizard.

Product(s) Affected: WebLogic Server and WebLogic Express

Threat level: Low
The private key passphrase is displayed on a terminal or in the server log file.

Severity: Medium
The passphrase could be used to access private keys in the keystore.

A problem was identified that could potentially cause a security vulnerability in certain versions of WebLogic Server. An upgrade is available to correct this problem (see Section II). Oracle treats potential security problems with a high degree of urgency and endeavors to take appropriate steps to help ensure the security of our customers' systems. As a result, Oracle strongly suggests the following actions:
I. Read the following advisory.
II. Apply the suggested action.
III. If you know of any additional users interested in future security advisories, please forward them the registration instructions included in this advisory.

I. Advisory

All sites are susceptible to this vulnerability. The vulnerability occurs when a new WebLogic Server domain is created using the Configuration Wizard. The passphrase for the private key used in the configuration of SSL is echoed to the screen and in the server log file. A potential attacker could see the passphrase or with proper file access to the server log could obtain the SSL keystore passphrase. The attacker could then compromise the keystore (if the attacker had file system access to the keystore).

This issue is resolved by replacing the keystore passphrase with multiple * characters on the screen and in the server log file.

The following versions of WebLogic Server and WebLogic Express are affected by this vulnerability

  • WebLogic Server 8.1 released through Service Pack 3, on all platforms.

II. SUGGESTED ACTION


Oracle strongly recommends the following course of actions.

WebLogic Server and WebLogic Express version 8.1
  1. Upgrade to service pack 4.
